Toroidal trapped surfaces and isoperimetric inequalities
Janusz Karkowski, Patryk Mach, Edward Malec +2
We analytically construct an infinite number of trapped toroids in spherically symmetric Cauchy hypersurfaces of the Einstein equations. We focus on initial data which represent "c…

Rotating systems, universal features in dragging and anti-dragging effects, and bounds onto angular momentum
Janusz Karkowski, Patryk Mach, Edward Malec +2
We consider stationary, axially symmetric toroids rotating around spinless black holes, assuming the general-relativistic Keplerian rotation law, in the first post-Newtonian approx…
